The standard sequence is: verify the original, prepare the translation or certification in the required format, certify with the Department of Intellectual Property, then re-check before filing.
The baseline set is the original a trademark application (or an officially certified copy), a passport or ID copy of the holder, and a power of attorney if someone else acts for you.
Turnaround depends on how complete the original is and on the authority's queue at the time, so treat any figure as an approximate range and avoid booking travel before the papers are in hand.
The final certification sits with the Department of Intellectual Property; document preparation and translation can be arranged in advance from Bangkok or upcountry.
Preparation and draft review can run online, but many authorities still require the physical original at the certification stage, so confirm the accepted format in writing first.
If you are outside Bangkok you can courier the original a trademark application, enclosing a passport copy and a contact number in the same envelope.
Rush handling can only compress the parts we control, such as drafting and courier legwork; the authority's own queue is outside anyone's control.
The most frequent causes are a name spelling that differs from the passport, an original older than the receiving body allows, and a translation that omits seals or the final page.
Once certified, the a trademark application is accepted by the receiving body it was prepared for; if the destination changes, re-check the certification format required.
From overseas you can appoint a representative in Thailand; the power of attorney must first be certified in the form the receiving authority requires.
Prepare at least one spare set: receiving bodies usually retain the certified original, and producing more later means repeating the certification steps.
A representative needs a power of attorney plus ID copies of both parties, and the Department of Intellectual Property will check that names match the source document.

Need your documents reviewed or your case assessed? Ask our team by phone, LINE, or email. We reply during business hours (Mon–Fri 9:00–18:00, Sat 9:00–15:00, ICT).

Trademark, patent, copyright and dispute-related documents used abroad must be translated with consistent technical terminology and certified along the route the receiving authority requires.
Prefer not to handle the queues yourself, or worried about a rejection? Send us photos of your documents for a free pre-check. We handle the full chain — obtaining certified copies, translation, certification and submission — and keep you updated at each step. Reach us on LINE, phone or email during business hours.
Registration and enforcement are different exercises, and the gap shows sharply once infringement happens.
| Route | When to use | Certifying authority | Approx. duration | Rejection risk |
|---|---|---|---|---|
| Register a trademark or patent in Thailand | You need rights enforceable primarily in Thailand | Department of Intellectual Property, Ministry of Commerce | Highly variable by right type and any opposition | Filing in classes that do not cover actual use narrows enforcement more than expected |
| International filing (Madrid or PCT systems) | You want coverage in several countries from one application | Department of Intellectual Property as receiving office, with WIPO | Variable by designated country | Each country still examines under its own law and may refuse individually |
| Infringement action or customs recordation | Infringement appears in the market or counterfeits are being imported | Central Intellectual Property and International Trade Court, and Thai Customs | Highly variable | Weak evidence of use and registration puts you on the back foot from the first hearing |
Timelines above are practical estimates from live casework and can change with each authority's policy; confirm with the receiving authority before booking travel. If you would rather not test routes by trial and error, our advisers can assess which route fits your case.
Our team has worked on cross-border documents, certified translation and government liaison for over 15 years. Most rejections we see are not caused by missing paperwork but by choosing the wrong route on day one, so we always start with a case assessment.
We look at your destination, purpose and deadline, then tell you which certification route applies — and which steps you can skip.
Name spelling, consistency across documents, document age and translation format are checked before anything reaches a counter.
We sequence the steps around your appointment or travel date and flag bottlenecks in advance.
We read the refusal reasons, identify the underlying cause, and plan a resubmission that answers what the authority asked for.

Different claims carry different prescription periods under the Civil and Commercial Code. Knowing when the clock started dictates whether to negotiate, send a demand letter, or file immediately.
One dispute can raise both. They use different courts, procedures and standards of proof; choosing the wrong track wastes time and cost.
Thai courts offer mediation before and during proceedings. A compromise agreement recorded by the court is enforceable and usually far faster than a full trial.
Chats, emails and transfer slips should preserve timestamps and identifiable parties. Foreign-language documents need a Thai translation to be used in court.
Thailand has no common-law notary. Certification is performed by a Notarial Services Attorney registered with the Lawyers Council of Thailand. If your recipient insists on a Notary Public, confirm acceptance in advance.
No lawyer or provider can guarantee a judgment, and advertising guaranteed results conflicts with professional conduct rules. What can be assessed is risk, relevant precedent and settlement options.
Posting party details or allegations while proceedings are live can create separate defamation exposure and damage the underlying case.
Translations used in court or before agencies must be certified by the translator, and in some cases legalised by the Department of Consular Affairs. Machine translations are commonly rejected.
Requirements differ by authority and destination country and can change. Confirm current conditions with the receiving authority, or ask our team by phone, LINE or email.
